## Examples
The following example uses a random number generator to emulate a data collection application that reads 10 integral values from eleven different instruments. A value of zero indicates that the measurement has failed for one instrument, in which case the operation should be cancelled and no overall mean should be computed.

To handle the possible cancellation of the operation, the example instantiates a <xref:System.Threading.CancellationTokenSource> object that generates a cancellation token which is passed to a <xref:System.Threading.Tasks.TaskFactory> object. The <xref:System.Threading.Tasks.TaskFactory> object in turn passes the cancellation token to each of the tasks responsible for collecting readings for a particular instrument. The <xref:System.Threading.Tasks.TaskFactory.ContinueWhenAll%60%602%28System.Threading.Tasks.Task%7B%60%600%7D%5B%5D%2CSystem.Func%7BSystem.Threading.Tasks.Task%7B%60%600%7D%5B%5D%2C%60%601%7D%2CSystem.Threading.CancellationToken%29?displayProperty=nameWithType> method is called to ensure that the mean is computed only after all readings have been gathered successfully. If a task has not because it has been cancelled, the call to the <xref:System.Threading.Tasks.TaskFactory.ContinueWhenAll%2A?displayProperty=nameWithType> method throws an exception.
